Adobe After Effects Animation and Keyframes 1 — Questions and Answers
Question 1: What keyboard shortcut toggles the visibility of keyframes on a selected layer in After Effects?
- U (Correct answer)
- K
- J
- L
Correct answer: U
Pressing U reveals all keyframed properties on the selected layer.
Question 2: Which interpolation type creates a smooth ease-in and ease-out between keyframes?
- Easy Ease (Correct answer)
- Linear
- Hold
- Auto Bezier
Correct answer: Easy Ease
Easy Ease applies both ease-in and ease-out Bezier handles for smooth transitions.
Question 3: What does the Graph Editor in After Effects allow you to control?
- The speed and value curves of keyframe interpolation (Correct answer)
- Layer blending modes
- Audio waveform editing
- Color grading curves
Correct answer: The speed and value curves of keyframe interpolation
The Graph Editor displays value and speed curves so you can fine-tune keyframe interpolation.
Question 4: Which type of keyframe maintains the same value until the next keyframe, then jumps instantly?
- Hold (Correct answer)
- Linear
- Easy Ease
- Continuous Bezier
Correct answer: Hold
Hold keyframes freeze the property value and jump abruptly to the next keyframe's value.
Question 5: What is the purpose of the Motion Path in After Effects?
- It visualizes the trajectory of a layer's Position keyframes in the Composition panel (Correct answer)
- It shows the audio path of a sound layer
- It displays the render queue order
- It tracks camera movement in 3D space
Correct answer: It visualizes the trajectory of a layer's Position keyframes in the Composition panel
The Motion Path appears as a dotted line in the Comp panel showing the spatial path of position keyframes.
Question 6: When you set the first keyframe for a property, what does After Effects do automatically when you change the property value later in time?
- Creates a second keyframe at the current time indicator position (Correct answer)
- Deletes the first keyframe
- Applies a hold interpolation to all keyframes
- Resets the property to its default value
Correct answer: Creates a second keyframe at the current time indicator position
After Effects automatically adds a new keyframe whenever you change a value while keyframing is active.
